This invention relates to roller bearings.

In the drawings accompanying and forming a part of this application I have shown certain illustrative embodiments of my invention, wherein Fig. 1 is an end elevation of a complete preferred bearing structure, and Fig. 2 a sectional View corresponding to the line 2-2 of Fig. 1; Figs. 3, 4, and 5 illustrate steps in the process of assembling such bearing; Fig. 6 is a sectional View corresponding to the line 66in Fig. 5; Fig. 7 is a detail view of a slightly modified bearing; and Fig. 8 is a perspective view of one spacer.

My improved bearing comprises two 00-- axial interfitting faces spaced radially apart and receiving between them the cylindricalbodied elements 12 and 13. These elements are arranged closely side by side around the l smaller member in the space between the two members, and alternate elements are formed at both ends with enlarged integral heads 14 which overlap the ends of the intermediate" elements and the end faces of the members 10 and 11. .Preferably the diameters of the.

1 body portions of the elements 12 and 13 are tomary in bearings) and all the intermediate elements being slightly smaller so as to have that the headed elements have the smaller bodies but this is not imperative, since they can be made larger or all of one size. Thein: ner shoulders of the heads are preferably 9 slightly rounded as indicated at 15 to preis completed, which necessarily occurs before sides. as shown at 14 unequal by a few thousandths of an inch, all. .ofthe load-carrying elements being of one size (within such tolerance-limit as is cusa spacing function only. It is my preference vent biting the adjacent parts and the distance between said heads is as much greater than the axial dimension of the members 10 and 11 as the. axial looseness desired. I have shown the two members as of equal axial dimension but this is not obligatory, and I have also shown the elements 12 as slightly shorter than this it dimension although this also is capable of variation so long as the same fit loosely in the space between the 0 heads 14. Also I have shown the bodies of the element 13 as formed between their ends with reduced portion 16 to afford more space for lubricant, but this is also a variable refinement. I a When the bearing is completely assembled the inner member 10 is completely surrounded I by elements 12 and 13in alternation. The mode of assembling requires special consideration. First the member 10 is placed inside the member 11 but eccentrically as shown in Fig. 3 to enable the introduction ofthe headed elements; this enables free introduction of such elements until 180 of the circumference all the headed elements have been introduced. As soon as enough such elements have been introduced to subtend 180 the member 10 is moved to a central position as shown in Fig.

4, after which the remaining elements (always at least one and in some cases more than one) a are inserted by. having one of their heads flattened or partly ground off on opposite Next the elements 12 are introduced,one between eachpair of head 8 edelements, which is easily done b handun- 1 til the last suchelement 12 is reac ed, which is forced into place between two headed elements whose heads are notched flattened, or

ground away for the purpose as shown at 14 in Figs. to6, or at 14 in Fig. In other words the jnotching to prevent theinsertion of the plain roller can either be independent of the flattening to permit the insertion of the last headed roller or it can be combined therewith. The last element 12 is preferably tapered slightly at its entering end as shown at 12 in Fig. 6, and if pressed into place by machine produces a hearing which cannot be dismantled. Such tightness of fit is, how- 3 ers vhavingsome part of their heads now c1 r'-" j cularlf I I I i V l I '1 F ever, not necessary since the form of bearing and hence within the i tent of these myLethere flattening 0r notching is necessary for" purposes of assembling, but it is, within-the limits of complete operativeness and high utility to make them all flattened or notched;
